. BUILDING TRUSS.

Application filed' February 20, 1926. Serial No. 89,678;

My present invention relates to the building construction and more particularly to an improved building truss. I r

The ordinary construction of steel trusses,

while eficient, is not adapted for use in situations where the surfaces of the metal will be exposed to the action of gases, moisture, etc., and this is particularly true in structures intended as kiln sheds. In the or- H) dinary truss the method employed in fabricating the same leaves a large number of cracks, crevices, etc., between the various members constituting the truss and it isimpossible to so cover up these cracks as to prevent the moist gases from contacting with and rusting the same, and thereby weakening the structure within a comparatively short time. This is particularly true where gusset plates are utilized to any extent. In

to my present invention I have obviated the objeetions to prior forms of trusses and have devised a truss for building constructions wherein all surfaces are exposed andcan be readily covered with paint. Those portions crevices are covered in my new structure in a bedding of cement or like material and therefore there is no crack or crevice left in which gases, or moisture can enter and rust the material. In carrying out my invention I preferably employ angle iron in making up the truss, as such form of material is readily and easily fabricated and can be handled in a shop without expensive tools or machinery. IVhere a deep form of girder or like element is desired, I utilize an angle iron in connection with a steel plate and ,by the aid of gusset plates am enabled to economically and quickly fabricate structures of any size and strength.

The object of my invention therefore is an improved truss for building structures.

In the accompanyingdrawings,

Figure 1 is a side elevation of one end of a building truss. i

Fig. 2 is a sectional end elevation on line 22 of Fig. 1 and Fig. 3 is a sectional elevation on the line 3-3 of Fig. 1. V

Referring to the drawings, 10 and 11 designate angle members of any suitable dimen sions as regards thickness and length, said angles being placed parallel with each other and between such members is placed a plate of the metal formerly hidden in cracks and 12 of steel as long as the angle members 10 and 11 themselves. Rivets 13 are employed to firmly unite the angle members 10 and 11 andthe steel plate 12 into a steel girder,

which extends throughout the length ofthe truss. 14 and 15 designate angle members of suitable dimensions securely fastened together, by rivets 16. The elements 14, 15 and 16 constitute a beam on which is supported the roofing boards of the building. The lower end of the beam formed of the elements 14, 15 and 16 is secured to one end of the girder comprised of the members 10, 11 and 12, thru the medium of the gusset plate 17 and rivets 18, as clearly shown in Fig. 1, and the upper end of the beam formed of the members 14, 15 and 16, is secured by riveting to a gusset plate 18 and to the central portion of the gusset plate 18 is riveted the upper end of a vertically arranged angle member 7 19, the lower end of the member 19 being riveted to the plate 12 associated with the angles 10 and 11.

In order to provide the necessary supporting members between the girder above referred to and the beam comprised of the members 14, 15 and 16, I rivet to one of the angle members 10 and 11, and preferably 11, as shown in Fig. 3, gusset plate 20, this gusset plate lying parallel to and spaced apartfrom the plate 12 a distance equal to the thickness of the metal in such angle member 11. The space between the gusset plate 20 and the plate 12 is filled with a water: proof cement of any desired kind, this cement being designated by the numeral 21 in Fig. 3. The use of this cement prevents the formation of a pocket in which moisture may collect and also obviates the necessity ofhaving a space between the members 20 and 12 that is inaccessible to either a scratch brush or paint. .To the outer face of the gusset plate 20 is secured, preferably by riveting, an, angle brace 22, while secured to the inner face of the gusset plate 20 above I the level of the plate 12, is the lower end of the space between the horizontal portion of the angle 15 and the upper edge of the gusset plate 24 is filled With a Waterproof cement 25 and therefore the space that is ordinarily left to accumulate moisture and to be acted on by moisture and gas, is not present in the present structure.

It will be obvious from the above description that With my improved method of constructing trusses that the resulting truss has every portion of the exposed metal readily accessible. Those portions that must be hidden because of close proximity to adjacent pieces are filled with a Waterproof cement. l/Vhile I say Waterproof cement, it is obvious that any other material suitable for the purpose may be employed.

Having thus described which I claim as new, is: 4

An improved truss including a girder, formed of a pair of angle members and plate lying between and secured thereto, a gusset plate secured to one of the angle members my invention,

and lying parallel to the centrally located plate and a filling means lying in the space formed between the gusset plate and centrally located plate.

In testimony whereof, I have name to this specification.
